The murder trial of Karmelo Anthony has attracted national attention, raising concerns about self-defense, race and accountability.
The Texas teenager was sentenced to 35 years in prison on Tuesday, June 9, for fatally stabbing a fellow athlete during a high school competition in suburban Dallas.
When did Karmelo Anthony stab Austin Metcalf?
The incident took place on April 2, 2025, when Anthony, then 17 years old, attended a high school track meet at Kuykendall Stadium in Frisco, Texas.
Just as the rain began to pour down, Anthony took shelter under the canopy assigned to competing Memorial High School, where Austin Metcalf was also a student.
It is clear from testimony that Metcalf and his gang urged Anthony to leave the area. According to police accounts, Anthony went through her purse and said, “Come touch me and see what happens.” Upon touching him, Anthony pulled out a knife and stabbed Metcalf in the heart. The two young people did not know each other.
Why did Karmelo Anthony stab a fellow athlete?
Both sides present very different explanations for why Anthony stabbed Austin Metcalf. Prosecutors argued that Anthony was the aggressor. They said he provoked Metcalf and then used deadly force in response to a simple push. This indicates a disproportionate reaction that amounted to murder. Throughout the trial, prosecutors maintained that Anthony intentionally killed Metcalf without any legal justification.
The defense, however, argued that Anthony’s reaction was self-defense. Anthony’s attorney referred to Texas law that does not require waiting until you are hit. The defense argued that Anthony felt threatened and reacted to protect himself.

- June 8, 2026: The defense rests without Anthony taking the stand. His mother, Kayla Hayes, testifies and says her son is “very sorry.”
- June 9, 2026: The jury found Anthony guilty within three hours. The same day during the sentencing, his mother asks for mercy and states: “He is my firstborn. Please have mercy on my son.”

Key evidence
Prosecutors supported their argument with testimony from the medical examiner, who described a larger open wound in Metcalf’s chest, with the knife piercing his heart.
final verdict
The jury rejected both the self-defense claims and the request for a lesser charge of manslaughter. Metcalf’s father, Jeff, told Anthony after the sentencing: “You failed yourself, you failed your parents, and you failed society.”
